Undetermined Problems (WP z50 - 2608)


Undetermined Problems

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative.

Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs).
Verify that all attached devices are supported by the WorkPad z50.

Verify that the power supply being used at the time of the failure is operating correctly.
(See 'Power Systems Checkout'.)

  1.  Enter suspend mode.
  2.  Visually check them for damage. If any problems are found, replace the FRU.
  3.  Remove or disconnect all of the following devices:

    1.  Non-IBM devices
    2.  Devices attached to the cradle
    3.  External devices
    4.  Battery pack
    5.  DRAM
    6.  PC Cards
    7.  Compact Flash Cards

  4.  Turn on the WorkPad z50.
  5.  Determine if the problem has changed.
  6.  If the problem does not reoccur, reconnect the removed devices one at a time until you find the  failing FRU.
  7.  If the problem remains, replace the following FRUs one at a time.
     Do not replace a nondefective FRU.

    1.  Mainboard
